Time constant matching error tolerance (TOB TCMatching)
●
Inductance and capacitance Tolerance (k
L
, k
C
). Variations in the inductance value and
in the value of the capacitor used for the Time Constant Matching causes over/under
shoots after a load transient appliance. This impacts the output voltage and then the
TOB. Since all the sense elements results to be in parallel, the error related to the time
constant mismatch has to be divided by the number of phases (N).
Capacitance Temperature Variations (k
Ct
). The capacitor used for time constant
matching also vary with temperature (
T
C
) impacting on the output voltage transients
ad before. Since all the sense elements results to be in parallel, the error related to the
time constant mismatch has to be divided by the number of phases (N).
All these parameters impact the Dynamic AVP, so they must be weighted on the
maximum dynamic voltage swing (I
dyn
). Total error due to time constant mismatch
results:

Temperature measurement error (V
TC
)
Error in the measured temperature (for thermal compensation) impacts on the output
regulated voltage since the correction form the compensation circuit is not what required to
keep the output voltage flat.
The measurement error (
ε
Temp
) must be multiplied by the copper temp coefficient (
α
) and
compared with the sensing resistance (R
SENSE
): this percentage affects the AVP voltage as
